Setting up incoming calls

Hello,

I do have my SIP trunk setup for outgoing calls. But, my SIP provider wants to test an incoming call. I do not have a physical sip phone yet. Can i use a softphone dialer from my mobile phone to configure with asterisk and use it for incoming calls? Will it work?

I have not done this before (incoming call setup). Is there any guide/steps for configuring incoming calls ?
